KALYVEX — ESCO: Solar Power Plants for Communities
KALYVEX implements “ESCO: Solar Power Plants for Communities” without upfront budget costs.
Intelligence-driven energy modernization of municipal infrastructure.
Measurable savings, online generation monitoring and accountability for the result.
Energy service as an investment in the future
The company KALYVEX implements complex projects ESCO: solar power plants for communities, municipal institutions and critical infrastructure facilities. The model includes an energy audit, financing, licensed installation, service and savings monitoring without upfront costs from the local budget. Investment recovery comes from verified reductions in electricity and other energy-resource costs.
Our focus:
- Installation of solar power plants and BESS energy storage systems.
- Thermal modernization of schools, kindergartens and medical facilities.
- Implementation of smart street-lighting systems.
- Modernization of boiler houses for renewable energy sources.
- Installation of automated energy-consumption monitoring systems.
Why this is relevant now
High costs
The cost of electricity, heat and infrastructure maintenance is growing faster than local budget capacity.
Critical infrastructure
Hospitals, water utilities, schools, lighting systems and boiler houses need stable operation even under energy-risk conditions.
Limited budgets
ESCO allows modernization to start without upfront capital expenditure from the community budget.
How a community moves through an ESCO project
Initial facility screening
We analyze a school, kindergarten, hospital, boiler house, pumping station or lighting system. We check bills, tariffs, technical condition and savings potential.
Energy audit and baseline
We record current consumption, define the baseline, calculate technical measures, savings and the forecast contract term.
Financial model
We show the investment amount, payback period, expected savings, the ESCO payment share and the final effect for the community budget.
Terms approval
We prepare the technical part, essential contract terms, efficiency calculation and data package for energy-service procurement.
Procurement via Prozorro
The client conducts procurement. Evaluation covers not only equipment price, but proposal efficiency and the size of guaranteed cost reduction.
Installation, service, savings
KALYVEX finances, installs, commissions and services the equipment. Payment is formed from verified savings after launch.
Indicative ESCO project launch timeline
1–2 weeks
Initial analysis of bills, tariffs, operating schedule and the facility’s technical condition.
2–6 weeks
Energy audit, baseline, financial model, list of measures and preliminary contract term.
1–3 months
Approvals, procurement preparation, essential contract terms and the Prozorro procedure.
1–4 months
Supply, installation, commissioning, service and the start of regular monitoring of verified savings.
Timelines are indicative. Actual duration depends on the quality of source data, the facility’s technical condition, the client’s readiness for procurement and the complexity of approving contract terms.
Financial logic in a simple example
Current annual energy costs of the facility
Potential annual savings after modernization
Upfront equipment cost for the community
Savings remain with the community after the contract ends
The logic is simple: the investor finances modernization, and investment recovery occurs not through a new budget payment, but through verified reductions in energy-resource costs. If there are no savings, there is no economic basis for payment.

| Model | Community upfront costs | Who bears result risk | When it fits |
|---|---|---|---|
| ESCO | Zero or minimal | Contractor / investor | There is stable consumption, metering and predictable savings |
| Budget financing | High | Community | There are budget funds, design documentation and a political decision |
| Grant | Depends on conditions | Community / donor / contractor | There is a competition, deadlines, co-financing and eligibility compliance |
| Loan | Medium or high | Community | There is creditworthiness, a payback forecast and readiness to assume obligations |
ENERGY SERVICE in numbers
Indicators are approximate and depend on tariffs, operating mode, equipment condition, consumption baseline, contract term and the agreed savings-measurement methodology.
ESCO in Ukraine is already an operating mechanism
Contracts are already operating
Energy service is used by communities, public institutions and critical infrastructure facilities.
A legal framework exists
The procedure has a legal framework, budget mechanism, contract model and procurement through Prozorro.
Practical results exist
The model works best where consumption is stable, savings are measurable and there is a long-term need for modernization.

Model cases for initial screening
School or kindergarten
Typical solution: solar power plant for daytime consumption, LED, heat automation and monitoring.
- ✓ Pre-modernization costs: electricity + heat
- ✓ Savings benchmark: after audit and baseline approval
- ✓ Risk: seasonality and operating-schedule changes
Water utility or pumping station
Typical solution: solar power plant, dispatching, peak control and pump-operation analysis.
- ✓ Pre-modernization costs: electricity for pumping equipment
- ✓ Savings benchmark: by actual load profile
- ✓ Risk: uneven consumption and emergency modes
Street lighting
Typical solution: LED luminaires, control cabinets, operating schedules and service.
- ✓ Pre-modernization costs: electricity + emergency maintenance
- ✓ Savings benchmark: by the number of lighting points
- ✓ Risk: grid condition and source-data quality
This is not a savings guarantee and not a commercial offer. The final calculation is made only after bill analysis, technical inspection, tariffs, operating mode and approval of the consumption baseline.
Which facilities are suitable for ESCO
Suitable
- Schools, kindergartens, hospitals, administrative service centers and administrative buildings.
- Facilities with high electricity, heat, gas or water costs.
- Buildings with stable operation and a clear consumption schedule.
- Street lighting, boiler houses, pumping stations and heat substations.
- Facilities where savings can be verified by meters or an agreed methodology.
Require separate analysis
- Buildings without consumption history.
- Facilities with unstable or seasonal operation.
- Emergency-condition buildings with no long-term operating prospects.
- Facilities where savings cannot be separated from external factors.
- Projects where payback exceeds the allowable contract term.
When ESCO will not work
Not suitable
- A facility without stable consumption history for 12–36 months.
- A building planned for closure, sale or major reconstruction.
- No commercial metering or the readings cannot be verified.
- Consumption is too low to pay back the investment.
- The client is not ready to provide bills, facility access and technical data.
What we do in that case
- We perform initial screening without launching a full project.
- We filter out weak facilities before the community spends time on them.
- We offer alternatives: grant, budget financing, loan or staged modernization.
How savings are verified
1. The baseline is defined
The pre-modernization consumption is recorded: kWh, Gcal, m³ of gas, m³ of water or cost equivalent in hryvnia.
2. Energy-efficiency measures are implemented
Equipment is installed: solar power plants, LED lighting, heat substations, automation, insulation, dispatching or other solutions for a specific facility.
3. Actual consumption is compared
After launch, actual readings are compared with the baseline while accounting for weather, operating schedule, load changes and other agreed factors.
4. Payment comes from verified savings
If savings are not achieved due to the contractor’s fault, the contractor remedies the deficiencies or bears responsibility under the energy-service contract.
Quick test: is your facility suitable for ESCO
- ✓ Energy bills are available for at least 12 months.
- ✓ Annual electricity, heat or gas costs are material for the budget.
- ✓ The facility will operate for the next 5–10 years.
- ✓ Meters exist or metering can be installed.
- ✓ A responsible person can provide technical data.
If at least 4 of 5 points are met, the facility should be checked for the ESCO model.

Frequently asked questions
Who finances the equipment in an ESCO project?
Financing is provided by the ESCO investor. The community does not pay for equipment at the start; settlement is made from verified energy-resource savings.
Who owns the equipment after the contract ends?
After the contract term ends, the modernized equipment transfers to the community under the contract terms. From that moment, all further savings remain in the local budget.
How are savings verified?
Savings are verified by comparing actual consumption after modernization with the consumption baseline defined before the project, accounting for agreed adjustment factors.
Which facilities are suitable for ESCO?
ESCO is suitable for schools, kindergartens, hospitals, administrative buildings, boiler houses, street-lighting systems, pumping stations and other facilities with stable energy consumption.
How is the quality of savings controlled?
Through the consumption baseline, actual meter readings, reporting and a monitoring system. The client pays for a verifiable result.
What happens if savings are lower than calculated?
This is recorded in reporting and regulated by contract terms. The contractor is interested not merely in installing equipment, but in delivering an actual result.
How long does project preparation take?
It depends on data availability, facility complexity, metering quality and the client’s procurement readiness. The fastest route is to provide bills, technical data and a responsible contact immediately.
